Now I have the same problem when starting the GhostBSD from the iso image. I tried adding the line

set hw.ata.ata_dma=0

at the end of the boot options, but the problem still persists.
After reporting the error a few times, the boot continue and I can get to the desktop and start the installer.
However, when the installer tries to format the disk, the error appears again and the installation is aborted.
